Description

  The present invention relates to a resin hinge cap, and in particular, whether or not a container has been opened at the distribution stage in addition to being able to close and open the mouth with a lid attached to the mouth of a container such as a bottle. The present invention relates to a resin hinge cap provided with an explicit virgin mechanism (unauthorized release prevention mechanism).

  A hinge cap with a resin lid is attached to the mouth of the container, and the mouth can be closed and opened by opening and closing the lid, making it easy to maintain the hygienic condition inside the container and the mouth even after opening the container. Products in containers that enable easy removal of the filling are widely spread.

  However, since the resin hinge cap can be easily exposed to the inside and outside of the container by simply opening the lid, the product attached to the container mouth can be easily distributed. In addition, since it is difficult to determine whether or not it has been opened, it is likely that the quality maintenance and reliability of the product are insufficient.

  With respect to this problem, a virgin mechanism is provided for clearly indicating that the package has been opened, as described in, for example, Japanese Patent Laid-Open Nos. 62-19950 and 2006-306471 and shown in FIG. The resin hinge cap 2C is known and has now become widespread.

  In such a resin hinge cap 2C, a cylindrical plug-like body 26 is firmly attached to a mouth portion of a container 1 such as a bottle so as to cover it, and a disc-like lid connected to the plug-like body 26 with a hinge. The body 27 can open and close an opening 26 a provided as a spout on the top surface of the plug-like body 26. Further, as shown in FIG. 6A, the lid body 27 and the plug-like body 26 are made of resin and connected via a strip-like strip 28 so as to maintain an unopened state. By gripping the grip means 28a with a finger and pulling in the centrifugal direction to break and separate, the connection between the lid 27 and the plug-like body 26 is released, and the lid 27 can be opened and closed.

  By providing such a virgin mechanism, it becomes possible to easily discriminate it when it is illegally opened in the distribution stage, so that the reliability of the product is ensured. However, since such a strip-shaped strip 28 has a length substantially the same as the length of the outer periphery of the resin hinge cap 2C, a relatively large amount of resin material is used. In addition, it is necessary to increase the plug-like body 26 by the width, and the raw material cost tends to increase as a whole.

  In recent years, the depletion of petroleum resources and the increase in global warming gas due to combustion have become a major social problem, and social demands to minimize the use of resin materials made from petroleum are also increasing. Therefore, it is preferable to minimize the portion that is discarded at the time of use even in the production of the resin hinge cap.

  FIG. 1 is a longitudinal sectional view showing a state in which a resin hinge cap 2A provided with a virgin mechanism according to the present embodiment is attached to the mouth of a container 1, and a partially enlarged view showing details of the virgin mechanism in a circle. It is. This resin hinge cap 2A is a plug-like body 21 made of a cylindrical member having an upper surface that is firmly mounted and fixed in a state where the inner peripheral surface is in close contact with the outer peripheral surface of the cylindrical mouth of the container 1 and that closes the mouth. And a disc-shaped lid body 22 that is connected to the upper surface edge side through hinges 21c and 21c so as to be openable and closable and covers the entire top surface of the plug-shaped body 21.

  A spout-like opening (spout) 21a is provided at the center of the upper surface of the plug-like body 21, and the inside and outside circulation of the container 1 is secured at this portion. In addition, a cylindrical protrusion 22a protrudes downward from the center of the lower surface of the lid body 22, and the protrusion 22a is fitted with the outer peripheral surface closely contacting the inner peripheral surface of the opening 21a when the lid body 22 is closed. Thus, the inner and outer sealed state of the container 1 at a predetermined level or higher is ensured. Further, a bending plate 21d that supports the lid body 22 while being bent at an intermediate position so as to connect the end edge side of the lid body 22 and the plug-like body 21 is attached.

  The above-described components are well-known components that are also found in the prior art, but the virgin mechanism described in detail below has the characteristics of the present invention. That is, the virgin mechanism provided in the resin hinge cap 1A of the present embodiment has a thickness direction (downward) of the lid 22 on the lower end side of the peripheral portion facing the portion where the hinges 21c and 21c of the lid 22 are connected. The engaging tongue piece 22c is provided on the opposite side of the upper end of the plug-like body 21 where the hinges 21c and 21c are connected, and the lid 22 is closed. The engagement hole 210 has a structure in which 22c is inserted so as not to be removed and engaged with the plug-like body 21 side.

  Referring to the circle in FIG. 1, the engaging tongue piece 22c includes an intermediate portion 211 in which the grip means 211a protrudes in the centrifugal direction and a tip portion 222 having a hook-like structure on the tip side. The window 210a is formed in a slit shape between the outer peripheral surface of the mouth portion of the container 1 and the inner peripheral surface of the plug-like body 21, and the peripheral wall of the plug-like body 21 is cut out at a predetermined width at the upper portion thereof. The container 1 is inserted into the engaging hole 210 from above so that it cannot be removed from the plug-like body 21, and the container 1 is not opened while the opening 21 a is closed with the lid 22 closed. The state is to be maintained.

  That is, the engagement hole 210 of the plug-like body 21 is provided with a convex portion 210b that narrows the slit width in the centrifugal direction at an intermediate position, and becomes thicker from the distal end side to the proximal end side and at a predetermined position. The tip portion 222 of the engaging tongue piece 22c having a hook-like structure formed with a step is inserted into the engagement hole 210 from above, and the tip portion 222 pushes and widens the protrusion 210b. The engagement tongue piece 22c cannot be removed by passing through.

  Further, at the boundary portion between the base end side (plug-like body 21 side) of the engaging tongue piece 22c and the intermediate portion 211, a thinner portion than the other portions is formed across the width direction of the engaging tongue piece 22c. A rupture groove 224 is provided, and a similar rupture groove 225 is also provided at the boundary portion between the intermediate portion 211 and the tip portion 222. As shown in FIG. 2, the grip means 211a of the intermediate portion 211 is picked with a finger and centrifuged. By pulling in the direction, the intermediate portion 211 is separated by reliably breaking at the positions of the breaking grooves 224 and 225.

  In the resin hinge cap 2A of the present embodiment having the virgin mechanism having such a configuration, the lid body 22 and the plug-like body 21 are obtained simply by separating and dropping the intermediate portion 211 of the engaging tongue piece 22c. Can be easily released, and the lid body 22 can be opened to open the opening 21a. At this time, the distal end portion 222 having the hook-like structure remains on the engagement hole 210 side on the distal end side of the intermediate portion 211.

  FIG. 3A shows a side view of the resin hinge cap 2A shown in FIG. 1 when not opened, and FIG. 3B shows a case where the intermediate portion 211 is broken and separated into an opened state. However, the present embodiment is characterized in that the presence or absence of opening in the container 1 can be easily and surely recognized depending on whether or not the intermediate portion 211 having the grip means 211a is present. It is excellent in maintaining the quality of the contents and ensuring reliability.
